This study investigates the composition and spatial distribution of benthic foraminiferal assemblages in the estuaries of the Mamanguape and Paraíba rivers in Northeast Brazil. Samples were collected from different sectors along both estuaries and analyzed for foraminiferal density, diversity, and species composition in relation to abiotic factors like salinity, temperature, pH, and sediment grain size. Results show that calcareous foraminifera dominate both estuaries, likely influenced by stable pH and salinity gradients. Additionally, the sediment composition of both estuaries varies from typical tropical estuarine patterns, with the presence of coarse and medium sands suggesting significant environmental dynamics. Statistical analyses confirm that foraminiferal assemblages reflect spatial environmental variations within and between the estuaries, underscoring the potential of foraminifera as bioindicators in coastal ecosystem assessments.

The problem of specifying representative specimens to serve as vouchers or ground truth specimens for species is viewed from a perspective of object recognition based on training using exemplars recognized by personal perception. In taxonomy, an ‘exemplar’ mirrors the hypodigm concept of Simpson, which refers to certain specimens being unequivocal members of a species. His concept has been discarded in most taxonomies because he did not provide procedures that distinguished it from ‘material’ or ‘sample’. However, his underlying view of a morphospecies was of a group united by shared character resemblances, probabilistically related. On this basis, the hypodigm of a taxonomic species is here restricted to specimens demonstrated as likely belonging to one population. To raise objectivity in this task, personal perception should be supplemented by morphometric analyses, several of which are demonstrated using living and Holocene samples of the oceanic zooplankter Truncorotalia crassaformis (Galloway and Wissler) from the Atlantic and Caribbean Oceans.

A review of the pore patterns of deep-sea benthic foraminifera is presented with a discussion of their characteristics, function and relationship with dissolved oxygen levels. Pore characteristics of deep-sea benthic foraminifera are of timely interest due to their potential for reconstructing dissolved oxygen conditions from the sedimentary record. Scanning electron micrographs of 20 epifaunal and infaunal deep-sea taxa from the Sulu Sea, Monterey Bay, California Bight and northwest Atlantic Ocean are presented to illustrate the wide range of pore patterns found in deep-sea taxa. New SEM observations of three taxa with biconvex test shapes, Oridorsalis umbonatus, Hoeglundina elegans, and Epistominella umbonifera, suggest that these taxa have an infaunal habitat for at least part of their life span.
